Integration with billing system.

RADIUS Connect-Info support (from 4.12.3).


Enforcement of time and/or volume subscriber quotas through the REST API.

From 4.11.3,  policy flow options to define traffic types not subject to quotas and to decide behavior when quota exhausted (blocking or slow down speed).

Metrics of congestion and traffic near top speed through the REST API.

Subscriber status table includes a warning counter of KPIs exceeding their threshold, to facilitate focusing on subscribers experiencing quality issues.

The DPI statistics can now be filtered by either IP Address or subscriber ID.

The main clients for each service can now be shown by either IP Address or subscriber ID.

The top subscribers by volume can now be shown by either IP Address or subscriber ID.

The latency per service graphs have been extended to 1 month (instead of just three days).

New dashboard alarms for NTP and forBilling Systems Synchronization.

New Automatic Congestion Management, based on advanced machine-learning algorithms, to automatically detect congestion situations and, in those case, apply a dynamic limit to mitigate the latency and packet losses caused by the congestion.

New Time Profiles, to allow specifying subscriber flow and rate policies as a function of the day-of-week and the time-of-day

Integration with Powercode billing systems

Integration with Cisco qos-policy RADIUS AVPs


Shaping policies per flow: it is now possible to set a limit per flow, in addition to existing combined limit to all flows of the same subscriber. Applicable to scenarios with NAT.

Sortable data tables more scalable.

In DPI Service Analysis, possibility to exclude DPI samples generated by monitoring policies (to eliminate biases caused by those policies, for example, because of full DPI of specific IPs).


Fixes the issue of slow speeds when doing shaping or rate-limiting when turning off overall TCPO.


Sortable data tables in:

  • Status->Flows->Per Subscriber
  • Status->Radius/REST->Subscribers
  • Status->Subscribers
  • Status->Policies
  • Statistics->Subscribers->Metrics

Administration->General settings

  • Host name
  • IPv6 prefix for subscribers
  • UDR production rate

Release Naming Conventions

BQN software release is identified by three digits (e.g., R4.1.1):

  • The first digit indicates a mayor release (e.g., Release 4). A major release requires new platform packages (normally it is not compatible with platform packages from previous major releases).
  • The second digit indicates a minor release within the major release (e.g., Release 4.1). Contains new functionality and it is compatible with the platform packages of its major release. Simply involves the installation of a BQN package.
  • The third digit is a patch number, delivering corrections of the minor release. This is the convention from R4.1 onwards (R4.0 was delivering also functionality using the third digit).
